11 Claims.

This invention relates to improvements in means for hondling feedstuffs, and has for its object to provide, in connection with a silo,means for delivering feed, such as hay, to a chamber and distributingthe hay to various parts of the chamber.

It also has for its object to provide a rotating platform onto whichfeed is delivered and from which it is distributed by rotation.

It is also an object of this invention to provide a rotating andtiltable platform for distributing hay and similar feed materials to acontainer. The platform not only tilts but rotates.

These and other objects and advantages will appear from the followingdescription taken in connection with the drawing.

This is a division of my copending application, Ser. No. 637,818, filedOctober 14, 1932.

Referring to the drawing:

Figure 1 shows the upper part of a feed storage building with the roofand the upper parts of the walls thereof in vertical section.

Figure 2 shows a section of the apex of the silo roof with a platformthereon, and a pile of chopped hay on the platform, which makes itdifficult to secure a perfect distribution of the hay.

Figure 3 is a section through the apex of the silo roof showing atilting and rotating .means 39 for distributing the chopped hay.

Figure 4 is a view similar to Figure 3, showing a modified form of meansfor tilting the hay distributing means.

Figure 5 is a view similar to Figures 3 and 4,

with still another modified form of means for tilting the haydistributing means.

Figure 6 is a section through the apex of the silo showing a deliverychute extending through the apex.

Figure '7 is a view showing the spout end of the chute.

The outer wall of the feed storage building is indicated by the numeral1, and has inside thereof and closely adjacent it, a wall 2 formed ofhorizontally arranged spaced boards. Between the outer wall and the wall2 are studdings 3, which serve to support the boards that form thespaced wall and provide a space between the boards and the outer wall 1.

There is an inside wall 4. which forms the silo part of the storagebuilding. Around the periphery and between the silo wall and the outsidewall 1, and adjacent the silo wall, is a spaced wall 5 composed ofhorizontally arranged boards supported on studdings 6 which provide aspace between the boards and the inner wall for the circulation of air.

Resting upon the outer wall 1 is the usual roof 7. In the presentinstance the walls are circular in shape and have mounted above them forprotection a cone-shaped roof. Inone side of the roof is a dormer window8, while in the apex of the roof there is an opening circular in shapein which there is located a centrifugal collector 9. Below thiscentrifugal collector is a cone 10 which terminates in a spout 11.

On top of the centrifugal collector is an outlet opening 12. There isconnected to the centrifugal collector a pipe 13 through which hay and.any other feed material may be transmitted into the collector, and fromthe collector discharged through the spout 11. In the collector thematerialis given a centrifugal motion, due to the force of the air usedto drive the material into the collector, which tends to remove dust andsuch material from the hay and discharge it'out at the opening 12 sothat the hay is delivered into the interior of the buildingsubstantially free from dust and such-materials. The free end of thepipe 13 is supported by means of a rope 16, which passes over a pulley15 supported on a platform 14 attached to one side of the building.

On the silo wall is a cone-shaped roof 1'7, which has in its apex anopening 18. In this opening is a circular frame 19. This frame may beused for supporting one end of each rafter used for supporting the roof17, while the other ends of these rafters are supported on the wall 4.

As shown in Figure 2, a platform 20 may be supported over the opening.18 in the frame 19. As shown in Figure 1, there is no means providedfor'distributing the hay which is caught upon the platform in a pile 21.The hay will be distributed from the platform in a haphazard way and notequally distributed to all parts of the compartment in which the hay isto be distributed. In order to avoid this haphazard and unevendistribution of the hay the platform may have mounted thereon a pedestalor stand 22.

This pedestal supports a vertically disposed shaft 26, which has on itsupper end a plate 23 supported by means of a pivot 24. This plate may beadjusted by means of a screw 25 passing through a slot in the arcuatebracket 25a on the lower surface of the plate. The plate is pivoted tothe upper end of the shaft 26 above the platform.

On the lower end of this shaft 26, below the platform, is a gear 2'7which meshes with a pinion 28 on the end of the shaft of almotor 29supported by means of brackets 30 on the under side of the platform. Theinclination of the plate 23 may be adjusted by the screw 25. This plateis shown in full lines in one position and in dotted lines in. anotherposition. When the plate has been properly adjusted with relation to theshaft 26 the operation of the motor will cause the shaft 26 to rotateand thereby rotate the plate.

This plate is located immediately beneath the spout 11 so that the hayor other material discharged from the spout will fall upon the plate,substantially over the shaft 26, so thatthe rotation of the plate willdistribute the hay to all parts of the annular chamber around the silopart of the building.

In the form shown in Figure 4 the platform is provided with a peripheralgroove .31, in which a rope 32 fits and operates for rotating theplatform. This rope passes over two guide pulleys 33 and is suitablyattached to some operating mechanism, not shown. In this form the plate23 is adjusted with relation to the platform by means of a spring 34 andan adjusting screw 35.

In the form shown in Figure 5 the plate is pivoted at one edge by meansof a hinge 37 to a platform 36 composed of the same material as theframe 19. Adjacent an opposite edge of the plate 23 is a bracket 38,which cooperates with a bracket 39 attached to the platform 36 forholding the plate 23 in adjustment. This adjustment is effected by meansof a screw 40, by which the brackets 38 and 39 may be adjusted'withrelation to each other to vary the amount of tilt given to the plate 23.i

In Figure 6 there is shown a discharge chute 41 extending throughthe'opening in the apex of the silo roof. In order to permit this chuteto be extended through the opening the platform and the parts supportedthereon are removed. On the lower end of this chute is a mouth 42, whichhas therein a plurality of fixed arcuate guide vanes 43. This chuteextends through the opening into the silo so that the material may bedelivered into the silo from the pipe 13.

Since the material delivered into the silo does not have to be spreadover such a wide territory a rotating plate is unnecessary for thedistribution of the material. It can be properly distributed by means ofthe arcuate guide vanes 43, located in the interior of the mouth of thechute.

The foregoing structures are such that an equal distribution of thefeed, such as hay and other similar feed materials, may be accomplishedto all parts of the building. In the case of the annular chamber thetilting plate and rotating platform serve to distribute the material toall parts thereof, while the material is distributed to all parts of thesilo by means of the arcuate vanes at the end of the chute.

It will be understoodthat I desire to comprehend within my inventionsuch modifications as come within the scope of my claims and myinvention.
